Be it known that JOHN PLATE, a subject of the King ot Sweden, residing at Chicago, in the county of Cook and State ot Illinois. have invented a certain new and useful Improvement ing Finely-Divided Material Such as Etc., ot which the following is a specication.

This invention relates to an apparatus tor 'drying nely divided material such as peat.

gravel, sawdust and the like, and has tor its object to provide a newr and improved device of this description. .Material like peut. for example, is widely distributed. lout it is diicult to properly, quickly and cheaply d rit so as to put it in condition for use as a el. One of the objects of my present in` vention is to provide an apparatus by means of which such material as peat may be easily, quickly and cheaply dried. The invention is illustrated in the accompanyingT drawings wherein Figure l is a sectional view through one form of device embodying the invention;

Figure 2 is a sectional view showing a modified construction ;A

Fig. 3 is a cross 'sectional view ot the receptacle sho/wn in Fig. 2.

yFig. 4 is a view showing fied construction.

Like numerals refer to like parts throughout the several figures.

Referring now to Figure l l have illustrated a receptacle l into which the material to be dried is received. This receptacle must be arranged so that water or' moisture wallsthereof, but the peat or other material cannot pass through such walls. In the construction shown this receptacle is provided with walls made of porous material. The receptacle, for eira'lnple, may be made ot concrete. stone, earthenware or 'the like. When the walls are a jfurther inodi ,made of such material l provide a retainingT or protecting device2'which may consist ot Ia wire net preferably of steel or other strong wire so as to take the strain when the receptacle is rotated, thereby preventing` in- -]ury to such receptacle due tocentrifugal force. Some suitable means provided tor rotating this receptacle. fin censtrnf:f

in Apparatus tor lryfy tion shown'there is a pulley 3 connected with the sleeve ,4 on the shaft 5, said sleeve being suitably connected with the receptacle so that when" the' pulley is rotated-the receptacle will be rotated. The receptacle l is preterahly open at the top and the bottom. and l" may provide rollers 6 located at suitwhile heini; rotated. The shaft 5 is mounted in suitable bearings 7 and 8 connected` with the trame 9. Located within the receptacle is a device for removing the material to be acted upon 'Fromthe walls of the receptacle. ln 1Figure ll have illustrated a screw 1 0 which is' rotatably mounted upon the sha-ft o; This shaft is provided with a pulley 1l hy means ot which it may be rotated so as to rotate'the screw 10. The material vis distributed over the inner surface of the wall or" the receptacle through the' agency ot this screw. The screw 10 is preferably provided at its periphery with some flexible material which engages the material on the walls of the receptacle. As illustrated l provide brushes i2 on the periphery ot-this screw. The peat-or other material is fed into the hopper l?. and then passes through the pipe lai into the receptacle l. ln Figure 2 l have shown a modified construction wherein the receptacle l5 which may be of any suitable porous material is provided with the steel net- 16 and is rotated by means of the pulley 'i7 connected with the rotating part 'i8 which in turn is connected with the receptacle arid which is mounted uponand rotates with the shaft i9. said shaft being mounted inhearings on the traine 20. there being suitable rollers 2l to keen the'receptacle in proper alignment. The peat or other material to he dried is placed inthe hopper-22 and passes down through the pipe S23 which has an enlarged end 24 preferably havin;r a narrow discharge opening so that.
